Hello everyone, I have a Lifelike C424 and if you are familiar with this locomotive there is a noticeable gap between the trucks and the under-frame. I remember seeing a how-to on what to do to fill this gap... I have read about people glueing a plastruct I-Beam to the side sill... I have searched the web and searched these forums but can't seem to find any info... If anyone knows or has a link they can share that would be great! Thanks.
